How Does a Double Suction Pipeline Pump Balance Axial Thrust?

Every centrifugal pump pushes on its own shaft. Water leaves the impeller at high pressure, and the same pressure presses back on the impeller's surfaces, trying to shove the whole rotating assembly along the shaft toward one bearing. A Dou...

SMWK Pipeline Cutting Pump: Design and Model Range

Pump designs often look similar from the outside, but their internal structures determine how they handle different liquids. In wastewater equipment, a cutting mechanism adds a specific function to the pumping assembly. The SMWK Pipeline Cu...

How Is a Multistage Deep Well Diving Electric Pump Sized?

A single impeller can only add a limited amount of pressure to the water passing through it. Lifting water from a deep well to the surface, or to an elevated tank, takes more pressure than one impeller can supply, which is why a Multistage ...

Stainless Steel Permanent Magnet Submersible Pump Targets Lower Energy Costs

Permanent magnets give a motor its efficiency advantage, but they also introduce a limit that induction motors do not share: magnets can lose strength if they run hotter than their rated temperature. A Stainless Steel Permanent Magnet Subme...

Submersible Sewage Ejector Pump Selection by Site Conditions

Define the Wastewater Duty Wastewater pumping projects differ in flow demand, discharge height, pipe layout, and the material carried in the liquid. A submersible sewage ejector pump should be assessed against these conditions rather than s...

Cutting Fluid Pump Life Depends On Blade Clearance

A Cutting Fluid Pump built around an integrated cutting mechanism has to do two jobs with the same rotating part: move fluid through the pipeline and chop whatever fibrous or solid material is suspended in it before that material ever reach...

Deep Submersible Pump Reliability Depends On What Stays Sealed

Everything that keeps a Deep Submersible Pump running sits fully underwater for the entire life of the installation, which means components that would get a quick visual check on a surface pump instead have to be engineered to go years with...

Multistage Centrifugal Pump Structure for Compact High-Pressure Systems

Industrial water systems often need higher pressure without adding a large horizontal footprint to the equipment layout. This requirement has made the Multistage Centrifugal Pump an important configuration for water boosting, industrial cir...

Stainless Steel Submersible Pump Design for High-Head Water Delivery

Water lifting requirements are not determined by flow rate alone. A project may need to move water vertically through a deep well, maintain pressure in a distribution system, or transport water through a longer pipeline. In these situations...
